What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the first function be represented as f ( x )
Let the second function be represented as g ( x )
Now , to solve a system of two equations graphically, we need to graph both equations on the same coordinate plane and find their point of intersection. This point represents the solution to the system
So , the point of intersection of the graphs is
A ( 2 , 0 ) and B ( 0 , -4 )
Hence , the solution is A ( 2 , 0 ) and B ( 0 , -4 )

1. x - 2y = 14
x + 3y = 9
2. y = 2x
5x - y = 9
Answers
Answer:
Step-by-step explanation:
x - 2y = 14
x + 3y = 9
subtract the first equation from the second to eliminate the x terms:
x + 3y = 9
-x + 2y = -14
-----------------
5y = -5
y = -1
x - 2(-1) = 14
x = 12
:::::
y = 2x
5x - y = 9
Substitute 2x for y in the second equation?:
5x - 2x = 9
3x = 9
x = 3
y = 6

The human body contains trillions of microorganisms — outnumbering human cells by 10 to 1. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass (in a 200-pound adult, that's 2 to 6 pounds of bacteria), but play a vital role in human health.

14/1 = x/1.99 what is this awnswer
Answers
Answer:
x = 27.86 thats the answer
Answer:
0.2786
Step-by-step explanation:
Solution Steps:
The following question is of the type "How much X percent of W", where W is the whole amount and X is the percentage figure or rate".
Let's say that you need to find 14 percent of 1.99. What are the steps?
Step 1: First determine the value of the whole amount. We assume that the whole amount is 1.99.
Step 2: determine the percentage, which is 14.
Step 3: Convert the percentage 14% to its decimal form by dividing 14 into 100 to get the decimal number 0.14: 14100 = 0.14
Notice that dividing into 100 is the same as moving the decimal point two places to the left. 14.0 → 1.40 → 0.14
Step 4: Finally, find the portion by multiplying the decimal form, found in the previous step, by the whole amount: 0.14 x 1.99 = 0.2786 (answer).
The steps above are expressed by the formula: P = W × X% 100. This formula says that: "To find the portion or the part from the whole amount, multiply the whole by the percentage, then divide the result by 100". The symbol % means the percentage expressed in a fraction or multiple of one hundred.

Answer:
24.3
Step-by-step explanation:
To find the perimeter of any figure you just add the sides together
figure A''B''C''D'' is congruent to figure ABCD therefore they have the same side lengths
so to find the perimeter we add
6+6+6+6.3=24.3
so the perimeter is 24.3

Step-by-step explanation:
.05N + .10D = 1.65
.05 is the value of the nickel and .10 is the value of the dime.
N + D = 21 because you have some combination of them that total 21
solve for N: N = 21- D
substitute into the first equation
0.5 (21-D) + .10D = 1.65
1.05 - .05D + .10D = 1.65
.05D = .6
D = 12 you have 12 dimes
21-12 = 9 nickels

What is the general equation of a Straight line?The general equation of a straight line is -
y = mx + c[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a graph as shown in the figure.
We can find the slope using a pair of coordinates. Let the two points be -
(50, 125) and (100, 250)
The slope will be -
m = (250 - 125)/(100 - 50)
m = 125/50
m = 2.5
Therefore, the slope of the graph is 2.5 and it represents the profit earned for each box of cookies sold.
